Definitions
- the present invention relates to the field of cables for transmitting and/or distributing electricity.
- the present invention relates to a method for making a splice between optical fibres in a device for forming a joint between electrical cables, particularly (but not exclusively) medium- or high-voltage cables.
- a cable for transmitting and/or distributing electricity typically comprises one or more conductive cores.
- Each conductive core generally comprises a metal conductor surrounded by an insulating layer and preferably by an inner semiconducting layer and an outer semiconducting layer.
- the conductive core or cores are in turn surrounded by a metal screen (generally made of aluminium, lead or copper), outside which a protective polymer sheath is provided.
- the term “medium voltage” refers to a voltage typically in the range from about 1 KV to about 30 KV, while the term “high voltage” refers to a voltage of more than 30 KV.
- a joint device generally comprises a sleeve which is fitted directly on the ends of the cables, and an outer protective casing in which the sleeve is housed.
- a sleeve fitted directly on the ends of the cables is described for example in patent application EP 0735639 A1 .
- An outer protective casing is described for example in patent application EP 21 13978 A1 .
- the sleeve may comprise different layers, each having a different function.
- a sleeve may comprise a tubular electrode made of a semiconducting material which performs the function of controlling the electrical field, a tubular insulator which covers the electrode, and an outer semiconducting covering which covers the tubular insulator and which performs the function of interconnecting the ends of the outer semiconducting layers of the two joined cables.
- the sleeve usually has a substantially cylindrical central portion and two substantially conical opposing end portions, through which the two cable ends enter the sleeve.
- the sleeve After the sleeve has been fitted on the joined cable ends, it is housed in the outer casing, which is typically made of a metallic material (such as copper), as described in the above mentioned patent application EP 21 13978 A1 , and which performs the function of ensuring electrical continuity between the metal screens of the two joined cables.
- the outer casing which is typically made of a metallic material (such as copper), as described in the above mentioned patent application EP 21 13978 A1 , and which performs the function of ensuring electrical continuity between the metal screens of the two joined cables.
- An electrical cable for transmitting and/or distributing energy can also comprise one or more optical fibres.
- the optical fibres can be used, for example, for transmitting data, or for monitoring the operation of the electrical cable.
- the optical fibres of an electrical cable are usually housed in a protective metal tube, which is in turn inserted among the metal wires of the metal screen of the cable.
- optical fibres When two ends of electrical cables comprising optical fibres are joined together, the optical fibres must also be spliced together.
- the kit comprises a splice tray which is housed in a suitable compartment of the outer casing. The compartment and the splice tray are accessible from outside the casing.
- the kit described above has a number of drawbacks.
- the need to provide a splice tray and a corresponding compartment for housing it disadvantageously entails an increase in the cost and overall dimensions of the outer casing, and therefore of the joint device as a whole. Furthermore, since the splice tray is positioned so as to be accessible from the outside of the casing, additional mechanical protection must be provided in order to protect adequately the optical fibres housed therein, and this further increases the cost and overall dimensions of the outer casing and therefore of the joint device as a whole. On the other hand, the accessibility of the splice tray from the outside of the outer casing is generally superfluous, since - once the splices have been made between the optical fibers - it is not normally necessary to carry out any other operation on the optical fibres.
- the aforementioned problem is resolved by a method for making a splice between optical fibres in a joint device for electrical cables, in which method the optical fibres emerging from the two joined cables are spliced together and their excess lengths are wound around the body of the sleeve in a helix which is substantially coaxial with the body of the sleeve.
- the ends of the optical fibres are spliced together firstly, and their excess lengths are then wound around the sleeve.
- the excess lengths of the optical fibres are wound in an open helix or " ⁇ " arrangement.
- the excess lengths of the optical fibres are wound around the sleeve firstly, and their ends are spliced together subsequently.
- the excess lengths of the optical fibres may be wound in either a closed helix or an open helix or " ⁇ " arrangement.
- a method for making a splice between optical fibres in a joint device suitable for housing a joint between a first electrical cable comprising a first optical fibre and a second electrical cable comprising a second optical fibre, the joint device comprising a sleeve having a cylindrical portion comprises: i) splicing the first optical fibre and the second optical fibre in order to form the splice; and
- step i) is performed before step ii), and step ii) comprises winding the at least a portion of the excess length of the first optical fibre and the at least a portion of the excess length of the second optical fibre around the cylindrical portion of the sleeve in an open helix or " ⁇ " arrangement substantially coaxial with the cylindrical portion.
- step i) is performed after step ii), and step ii) comprises winding the at least a portion of the excess length of the first optical fibre and the at least a portion of the excess length of the second optical fibre around the cylindrical portion of the sleeve in a closed helix substantially coaxial with the cylindrical portion.
- step i) comprises protecting at least one of the splice, the at least a portion of the excess length of the first optical fibre, and the at least a portion of the excess length of the second optical fibre, by means of at least one tube.
- step i) comprises, before splicing, fitting a first tube on the excess length of the first optical fibre so that the free end of the first optical fibre emerges through the first tube, and fitting a second tube on the excess length of the second optical fibre so that the free end of the second optical fibre emerges through the second tube.
- step i) comprises, before splicing, locking the first tube relative to the first optical fibre and locking the second tube relative to the second optical fibre by means of first fixing members.
- step i) comprises, before splicing, fitting a third tube on the first tube so that it is slidable relative to the first tube and so that the free end of the first optical fibre also emerges through the third tube.
- step i) comprises, after splicing, moving the third tube on to the splice and fastening the third tube to the first tube and the second tube by means of second fixing members.
- the first tube, the second tube and the third tube are made of flexible material.
- At least one of the first fixing members and the second fixing members comprises at least one strap.
